Transport system

Abstract

A transport system includes: a pair of first traveling rails (R 1 ) affixed to and laid on a floor (F 1 ); a pair of second traveling rails (R 2 ) laid on another floor (F 2 ) to be able to move in a laying direction thereof; a pair of intermediate traveling rails (RM) each including a first end and a second end, the first end being rotatably connected to an end portion of each of the first traveling rails (R 1 ), the second end being rotatably connected to an end portion of each of the second traveling rails (R 2 ); and a transport dolly (D) which travels on the first traveling rails (R 1 ), the intermediate traveling rails (RM), and the second traveling rails (R 2 ).

What is claimed is: 
     
       1. A transport system configured to transport a cargo between a floor and another floor which are disposed with a distance therebetween and are able to move relative to each other, the transport system comprising:
 a pair of first traveling paths configured not to move relative to the floor; 
 a pair of second traveling paths laid on the another floor to be able to move in a laying direction thereof; 
 a pair of intermediate traveling paths each including a first end and a second end, the first end being connected to an end portion of each of the first traveling paths or the floor such that the pair of intermediate traveling paths is rotatable in a horizontal plane, the second end being connected to an end portion of each of the second traveling paths such that the pair of intermediate traveling paths is rotatable in the horizontal plane; and 
 a transport dolly configured to travel on the first traveling paths, the intermediate traveling paths, and the second traveling paths. 
 
     
     
       2. The transport system according to  claim 1 , further comprising:
 a first guide rail laid parallel to the first traveling paths and affixed to the floor; 
 a second guide rail laid parallel to the second traveling paths and able to move in the laying direction thereof on the another floor; and 
 an intermediate guide rail including a first end and a second end, the first end being rotatably connected to an end portion of the first guide rail, the second end being rotatably connected to an end portion of the second guide rail, 
 wherein the transport dolly has a guide member movable along the first guide rail, the intermediate guide rail, and the second guide rail. 
 
     
     
       3. The transport system according to  claim 2 , wherein the guide member is provided with a guide roller which can roll along the first guide rail, the intermediate guide rail, and the second guide rail, and a roller bracket which supports the guide roller, and the roller bracket is mounted on the transport dolly to be able to rotate around a vertical shaft. 
     
     
       4. The transport system according to  claim 1 , wherein a traveling wheel of the transport dolly has a width such that the traveling wheel of the transport dolly can travel on each of the intermediate traveling paths when a gauge distance of the intermediate traveling paths is within a minimum value and a maximum value due to a relative movement of the first traveling paths and the second traveling paths. 
     
     
       5. The transport system according to  claim 2 , wherein a traveling wheel of the transport dolly has a width such that the traveling wheel of the transport dolly can travel on each of the intermediate traveling paths when a gauge distance of the intermediate traveling paths is within a minimum value and a maximum value due to a relative movement of the first traveling paths and the second traveling paths. 
     
     
       6. The transport system according to  claim 3 , wherein a traveling wheel of the transport dolly has a width such that the traveling wheel of the transport dolly can travel on each of the intermediate traveling paths when a gauge distance of the intermediate traveling paths is within a minimum value and a maximum value due to a relative movement of the first traveling paths and the second traveling paths. 
     
     
       7. The transport system according to  claim 1 , wherein a floorboard configured to cover a distance between the floor and the another floor is disposed at a portion below each of the intermediate traveling paths. 
     
     
       8. The transport system according to  claim 2 , wherein a floorboard configured to cover a distance between the floor and the another floor is disposed at a portion below each of the intermediate traveling paths. 
     
     
       9. The transport system according to  claim 3 , wherein a floorboard configured to cover a distance between the floor and the another floor is disposed at a portion below each of the intermediate traveling paths. 
     
     
       10. The transport system according to  claim 1 , wherein a cargo receiving section which receives a cargo from the transport dolly is disposed at the another floor in the side of the second traveling paths. 
     
     
       11. The transport system according to  claim 2 , wherein a cargo receiving section which receives a cargo from the transport dolly is disposed at the another floor in the side of the second traveling paths. 
     
     
       12. The transport system according to  claim 3 , wherein a cargo receiving section which receives a cargo from the transport dolly is disposed at the another floor in the side of the second traveling paths. 
     
     
       13. The transport system according to  claim 4 , wherein a floorboard for covering a distance between the floor and the another floor is disposed at a portion below each of the intermediate traveling paths. 
     
     
       14. The transport system according to  claim 5 , wherein a floorboard for covering a distance between the floor and the another floor is disposed at a portion below each of the intermediate traveling paths. 
     
     
       15. The transport system according to  claim 6 , wherein a floorboard for covering a distance between the floor and the another floor is disposed at a portion below each of the intermediate traveling paths. 
     
     
       16. The transport system according to  claim 4 , wherein a cargo receiving section which receives a cargo from the transport dolly is disposed at the another floor at a side of the second traveling paths. 
     
     
       17. The transport system according to  claim 5 , wherein a cargo receiving section which receives a cargo from the transport dolly is disposed at the another floor at a side of the second traveling paths. 
     
     
       18. The transport system according to  claim 6 , wherein a cargo receiving section which receives a cargo from the transport dolly is disposed at the another floor at a side of the second traveling paths. 
     
     
       19. The transport system according to  claim 7 , wherein a cargo receiving section which receives a cargo from the transport dolly is disposed at the another floor at a side of the second traveling paths. 
     
     
       20. The transport system according to  claim 8 , wherein a cargo receiving section which receives a cargo from the transport dolly is disposed at the another floor at a side of the second traveling paths.
